SHIFTER-ROD FOR POWER-DRIVEN MACHINES.

Specification of Letters Patent.

Patented Nov. 19, 1907.

- Application filed May.16. 1904. Serial No. 208.142.

To allfwhom it may concern;

Be .it knownthat we, MILLARD F. FIELD, of Winthrop, and EDGAR F. HATHA'WAY, of Boston, both in the county of Suffolk and Commonwealth of Massachusetts, have invented certain Improvements in Shifter- Ro ds for Power-Driven Machines, of which gaged by a worm on-the periphery of the on the same shaft with the a the following is a s ecification.

The invention re ates to shifter or -ship per bars and the. connection of such a bar with the driving mechanism and with an ad justable operative part in a power driven machine, and consists in a shifter-bar supported in bearings which permit both a rotary and a longitudinal sliding mevement of,

the bar, and in a swivel connection of the bar with interconnecting devices which control the driving mechanism, and a longitudinally sliding connection with means for adjusting another operative part in the machine.

In the drawings the improved shifterbar isillustrated as applied to a warp-drawing machine, wherein Figure 1 is an end elevation of such amachine; Fig. 2; is a front elevation of the shifter-bar and its connections and the upper part of the frame of the machine to which the shifter-bar bearings are attached.

Referring to the drawings, A is the frame of the machine; B, the standards which support the shifter-bar d and its bearings b upon arms b and certain operative parts of the machine, among which is the warp holding frame W supported by; and adapted to be adjusted longitudinally upon the grooved I rolls w The invention may be applied to a warp treating or warp drawing machine of any suitable type, as, for exam le, a machine wherein the old warp threa s are manipulated for union with new warp threads byrel-.

ative movement of means for operating upon warp threads in succession. In the disclosed type ofthe invention such relative movement is obtained by movement of means for operating upon the warp threads across the warp. If such operatm means he a for putting warpthreads through harness eyes, it may, if desired and in the present type of the invention, be 0 crate'd in accordance with the disclosure of t 1e patent to Field, No. 7 55,861,

Marf29, 1904, in which corrective or compensating or adjusting movement may be imparted to the warp holding frame as herein described.

The longitudinal adjustment of the frame W is controlled and effected by a toothed rack, not shown, on the rod F, which rack is enwheel f Up I wheelf, but obscured by it as located in Fig. 1, is a sprocket wheel, and upon the portion d of the shifter-bar D is another sprocketwheel (1. These two sprocket-wheels are connected by a sprocket-chain d; The sprocket-wheel cl is secured to a sleeve d, which latter is supported by and adapted to turn in one of the bearings b. For convenience' the shiftenbar D 1s made up of two portions, one d, which maybe of woodlarger than the other portion '11, which. may be of metal, securely attached to'the part d, by a rivet or any other convenient means, and fitted within the sleeve (i the sleeve and portion d of the shifter-bar being connected by a spline and groove or equiva ent means, by which-the portion 01 will be permitted to slide longitudinally in the sleeve, but the two will turn together when'the whole bar I), is

rotated. At the end of the shifter bar D opwhich the belt or clutch of the driving mechanism is operated. A ball and socket may be employed instead of the swivel joint.

By this construction of shifter-bar, the o erator is enabled to start and stop the macfiine by sliding the bar (Z longitudinally in its bearings, the part (1 sliding within the sleeve (1 and without changing the position of his hand, to rotate the bar, and thus for one portion of which swivel is pivotexample as illustrated, change the position of a warp-holding frame W for the purpose of ad-' justing the angle-or slope o fwarp-t hrea(.ls in relation to the warp-ieedingdevices in a warp drawing machine. As there-are occa .sions when these operations must be performed in quick succession, this constructwo of shifter-bar is an element of economy and a great convenience in the successful operatioi'i of a machine of this kind, and of any machine in which certain of its operative parts require close attention and. re-

- peatedquick adjustment as well as 'quick other cessation of the movement of the machine.
